Background technology

Vapour energy machine is a kind of machinery that can convert the energy of steam (liquids and gases) to rotating mechanical energy.Such as Wind energy conversion system, the hydraulic turbine and expanding machine directly or after converting energy into electric energy can drive driven machine.The hydraulic turbine, vapour energy machine and combustion The working medium of gas-turbine is respectively water, steam and combustion gas.Various vapour can be mechanical since action principle, structure type and purposes are different, The difference of the temperature of working medium used, flow and pressure is also very big, and according to operation principle, vapour energy machinery can be divided into positive displacement and power Formula：Type positive displacement steam mechanical can change swept volume to realize that energy converts by motor element；Dynamical type vapour can be mechanical by high Energy, also known as turbomachinery are converted in the interaction of power between fast rotating vane and steam.

It is well known that the energy of gas is mainly shown as molecular kinetic energy.Temperature is to characterize the amount of molecular motion severity, The namely mark of molecular kinetic energy.Air work mutually collides to generate power by the molecule of flood tide.The speed of molecule is bigger, The impact force of generation is bigger；The size for the power that object obtains depends on the speed and quantity of molecule.Gas in compression process, Volume-diminished, pressure increase, and simultaneous temperature increases.Similarly, gas expansion, pressure reduction, temperature also reduce.Temperature it So can be because the chamber wall shell moved in compression process has done work(to gas molecule with volume change；In expansion process The chamber wall shell that gas molecule externally moves has done work(.Therefore, the speed of container volume variation determines the width of gas temperature lifting Degree.

And the efficiency of traditional vapour energy machine is not high, efficiency only has 30-60% in practice.This is because：Fuel is in boiler After burning, chemical energy is released, and is converted into flame；Flame transfers energy to water again, generates the steam of high temperature and pressure.Steam Energy is mainly shown as molecular kinetic energy；Then steam is pushed to the acting of vapour energy machine blade again, and pressure and temperature is all reduced, but It is that vapor (steam) temperature does not drop to boiling point, the steam rich in energy that pressure does not drop to normal pressure is discharged, and eventually leads to vapour energy machine Efficiency reduce.
